PLANlNG-MACHINE.

SPECIFICATION forming part of Letters Patent No. 275,597, dated April 10, 1883.

Application filed November 14, 1882. (No model.)

To all whom it may concern:

Be it known that we, HENRY J. GoRDEs- MAN, J r., and JOHN R. THOMAS, both citizens of the United States, and residents of Oincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Planing-Machines, of which the following is a specification.

Ourinvention relates to an improved method of constructing and combining the feeding rollers in planing-machines, and also to an improvement in regulating the set of the rolls and applying pressure thereto, all of which will be fully explained in the description of the accompanying drawings, in which Figure l is a side elevation of our improvement applied to the frame of a planing-machine. Fig. 2 is a perspective view of the same; and Fig. 3 is a central sectional elevation of one of the upper-rollerjournals..

A A represent the frame of an ordinary planing-machine; B B, open columns, which form journal-guides, and which are securely attached to the frame A A.

0 represents the fixed feed-rollers; c, journals for the shaft of roller 0, which is adjustably set in the frame 0.

c 0 represent set-screws for adjusting the journals 0 in any desired fixed position.

D' represents the upper and movable pressure-roller, which is hung in L-shaped journalboxes d, the horizontal portion of which boxes slide vertically in the open space or ways provided in columns B. The stem or vertical portion .e of the boxes 11 have screw-threads tapped therein, as shown in Fig. 3..

E represents screw-rods tapping into the stems e, which must be a sufficient length to afford the necessary amount of vertical adj ustment ofthe roller D, which is effected by the turning of the screw-rods E.

F F represents bevel-wheelskeyed to screwrods E, and F similar gears, keyed upon the horizontal shaft G, journaled above the bevelgears F, as shown in Fig. 2.

H H represent bed-plates, which rest loosely on the top of columns B.

H represents ears or studs on which shaft G journals.

Screw-rods E likewise are journaled vertically through said plates H, and the gears, be

ing keyed through screw-rods E, suspend the pressure-rollers D adjustably on the plates H.

In order to allow yielding motion to roller D and apply a weight thereto to control the feeding pressure, columns B are pierced vertically from top to bottom with two holes, through which pass guide-rods I, as shown in dotted lines, Fig. 1. 1' represents the head of these rods 1, which rest on the top of plates H.

J represents cross-heads, to which the guiderods I are attached. The space between the lower roller, G, and the top of cross-head J is made sufficient to allow the yielding motion caused by the rising of roller D.

M represents scale-beams, attached by pivoted levers to cross-head J as shown'in Fig. 2. The drawings are shown as designed to empioy two weighted levers, M, or scale-beams, one under each cross-head J but it is manifest that the two cross-heads J may be connected together by a cross-beam, and the one weigted beam, M, attached thereto.

N represents a weight, adjnstably attached to beam M, so as to vary the amount of press nre-weight applied to the feed-roll D.

0 represents a hand-wheel,keyed upon shaft G, which is turned to adjust the roller D to any desired distance from the fixed roll C, and

it is usual to adjust the rolls nearer together than the thickness of the clear stuff planed, so as to apply suitable feed-roll pressure. When the lumber passes between the rolls 0 and D, the roll D, with its slidingjournals d,

rises, and with it plates 11 and their guiderods I and cross-head J, to which cross-heads are attached, the weighted lever exerting downwardpressure through these connections with the open columns B, pressure-roller D,

screw-rods E, and adjusting-gears F, to which the rods are keyed to revolve therewith, of the journal-boxes composed of the horizontal portion 11, in which the journals of the pressureroller revolve, and the vertical limb e, having screw-threads tapped into them, in which the lower ends of the rods 1'] screw, substantially as described.

2. The combination of open columns 13, pressure-roller 1), journal-boxes having vertical limbs 0, having scrcw-th reads tapped therein, screw-rods E, along which the boxes are adjustable, plates H, located on the upper ends of the columns and carrying the gears F, to which the screw-rods are keyed, said plates being connected with rods I, and serving as bearings for the screw-rods, cross-head J, and weighted lever M, whereby the plates carrying the gears F and screw-rods E can rise vertically, substantially as described.

3. The combination of the open columns B,

plates 11 on the upper ends thereof, carrying gears F and screw-rods E, which are keyed to the said gears,journal-boxes adjustable along said rods, the rods I, connected with the plates, cross-head J, and weighted lever N, whereby the top plates carrying the gears 1 and screw-rods E can rise and fall, substantially as described.

In testiomony whereof we have hereunto set our hands and seals in the presence of two subscribing witnesses.
